The .principal` objects of" the invention are, to overcome thedifficulties met with in the burning of oil fuel in the limited spaceafforded in boilers of the type used in steam a motor cars, and toprovide means for eiec tively eliminating the depositin of soot upon thetubes of the boiler, there y obviating the necessity of frequentcleaning of the boiler and enhancing its use.

The principal feature of the invention consists in the novelconstruction and ar rangement of a combustlon chamber for l a heatingsmall boi ers, such as are used in motor cars, tractors and likemachines, great care '1s experienced bythe precipitation of has a largecentral passage 2 theret andy the boiler is enclosed within a casing 3,f

M being spaced from the bottom and the outer walls thereof.

. A deflecto'r cone 4 is arranged centrally of the bottomof the casing 3to deflect the gases of combustion flowing f downwardly through thecentral passage 2 outwardl with a smooth flow and 'free from eddy cuirents.

The casing' 3 extends considerabl above the topof't e boiler and isprefera 1y provided with a dome top'5.

Within the dome 5 and spaced from the walls thereof is a circular casing`6 having a slightlyl arched top 7 and a central tubular extension 8extending downwardly from a the bottom to enter the central passage 2 ofVthe boiler. l

The lower end 9 of the tubular'extensio 8 is preferabl enlarged. .Aradial tu ular extension 10 flan es .directly in the path ofthe in\In'the use of li uid hydroarbon fuels for P is l formed on one side ofthe casing 6` and projects outwardl through the casing- 3 and is con-`necte with a suitable blower l1.

A fuel discharge nozzle 12 extends into the radial extension 10 of thecasing 6 and directs a finely atomized spray of hydrocarbon in to thecircular casing 6.

Directly opposite the inner end of the extension 10 is yarranged avertical portion 13 which is of V-shapehavingthe apex thereof directedtoward said .extension and the plro'ecting inwardly.

aped partition being` arranged owing air and atomized'oildividesthestream of the mixture, causing it to flow around the chamberin twouniform streams.-

Tis

Suitable means for igniting the mixture is provided, a spark plug 14being arranged close to the nozzle 12.

The burning mixture flows into the circu- Vlar combustion chamber, beingdirected around the same by the partition 13 vand the two streams offlame meeting op osite to the through the tube '8i The mixin df thecombustible materials effected by .t e division and then flowingtogether of theA llame ensures complete combustion of the mixture beforethe end of the tube 8 is reached so thatfno visible flame shows at thelower endv thereofy The hot asesproduced by the combustion are then'vided'uniformly b the cone 4 and directed laterally under t e bottom ofthemboiler to flow upwardly through the tubes and around the outer;side, passing over the top and flowing around the combustion chamberformed b the casing 6.

vIt will lie seen that the maximum heatingl value of the fuel lisobtained by the structure herein disclosed.

The present invention is shown and de-` oint of ingress yand flowingownwardlyi `understood that it may be ap- 1..In a fuel oil Y, urner, acombustion chamber having an inlet passage adapted to direct acombustiblef mixturev thereunto, a

central passage openin from the bottom of said combustion cham r,-andmeans disposed between said passages for dividing the flow ofmixture'directing it around the walls of ,the combustion chamber.

In a fuel oil-burner, a circular combustionchamber having a radialinlet, a diverging partition arranged opposite said inlet and dividing'the inflowing combustible mixture and directingfit around the inner wallof the combustion chamber,` and a central tubular outlet opening fromthe bottom of said combustion chamber immediately back of said divergingpartition, said partition effecting an indirect communication between'l5 the inlet and outlet.
